This is the Prophase.
<span>1) The chromosomes coil up and become visible while the nuclear envelope disappears.
2) Sister chromatids are appears.
3) A centriole forms at each pole and spindle fibers made of microtubules grow out of it.
4) Short microtubules stick out from the centriole in a star shape known as an aster.
I don't remember liking biology but I do remember some things from it.</span>
I claim light, water and minerals are the limiting factors that might affect the growth or diversity of our ecosystem.
Abiotic factors are the non-living components of an ecosystem and include light, minerals, water etc. These are the vital components without which an ecosystem cannot exist.
Light is essential not only for photosynthesis in plants, but also in maintaining a livable temperature on Earth. Day and night cycles affect and form all the organisms as well as the interactions between them .
Water in itself makes possible the process of photosynthesis in plants as well as the majority of chemical processes in living organisms. Furthermore, makes possible the absorbtion of soil nutrients by the plant roots. Without water, life would not be possible.
Minerals are trace elements that exist in all living organisms and are vital to the existance of life. They can be found in both organic and inorganic combinations and are responsible for the existance and functioning of all mental and physical processis. They are most important in maintaining all physiological process as well as acting as catalysts for many biological reactions.
Ecosystems are complex systems that are built on complex interactions between organisms and their physical environment. In order for any life to exist, certain conditions and requirements need to be fulfilled. Among these, light, water and minerals are vital to the existance of life. Without these three, life as we know it would not be possible. They shape both the ecosystem and the organisms living in a certain area. Their abundance dictates both the growth and diversity of our ecosystem.
Correct answer: D
A pollen is where male gametes are produced and so the number of chromosomes, as we are talking about gametes, is n. This means that the grain of pollen will only have a copy of each gene, and therefore only one allele for each gene - one S, and one T or t. So, the possible combinations are ST and St.
Answer:
I say, it would really be around like 50-500km. Really, it would be 70km.
Explanation:
Magma rises with convective currents, then cools and spreads intent on form ocean-floor crust. The place to start for melting has lengthy been idea to be at <em>70 kilometers</em> under the seafloor.
